Whether spiral steel pipe can be machined carbon steel pipe fitting

As we all know, many pipe fittings are made of steel pipes, especially the elbows. But the elbows are mainly made of straight seam steel pipes or cannot be made of steel pipes. Spiral steel pipes are not good, which mainly depends on the forming process.Spiral steel tube is a kind of spiral welded steel tube with strip steel coil as raw material, which is often shaped by warm extrusion and welded by automatic double wire and double submerged arc welding process.The spiral steel pipe feeds the strip into the welding tube unit, and after rolling with multiple rollers, the strip is rolled up gradually to form a round tube billet with an open gap. The reduction amount of the extrusion roll is adjusted to control the gap of the welding seam within 1~3mm and make both ends of the welding seam flush.

Therefore, the welding seam of the spiral steel pipe takes the shape of a spiral in the forming process, while whether the elbow needs to be extruded by a press during the processing or not, the spiral steel pipe cannot bear, so the raw material used for the elbow does not contain spiral steel pipe.
